中文摘要: 为解决尾砂利用率低下的问题,金山湾家坞矿区拟采用全尾砂来替代原有的废石和分级尾砂充填。基于此,需要对全尾砂中大量水进行脱水处理,因此开展了全尾砂充填脱水模拟试验研究,旨在探索出一条全尾砂充填快速脱水的有效途径。本文通过对定高度和不定高度分次充填渗透脱水情况进行试验研究,检测了渗水量、脱水含泥情况、脱水尾砂含水率等试验参数,探究出了金山金矿全尾砂脱水规律,建立起金山全尾砂滤水管渗透脱水的经验模型,为井下特大空区群充填脱水提供了技术支撑。
中文关键词: 空区充填  全尾砂  充填脱水  滤水管
Abstract:In order to solve the problem of low utilization rate of tailings, it is proposed to replace the original waste rock and classified tailings with unclassified tailings for filling in Wanjiawu mining area of Jinshan Gold Mine. Based on this, a large amount of water in the unclassified tailings needs to be dewatering. Therefore, study on the simulation test of dewatering in the unclassified tailings filling is carried out to explore an effective way for the rapid dewatering of the unclassified tailings filling. In this paper, through the experimental research on the osmotic dehydration of fixed height and unfixed height multiple filling, the test parameters such as the seepage water content, the dehydration mud content and the moisture content of the dehydrated tailings are detected, the dewatering law of the unclassified tailings in Jinshan Gold Mine is explored, and the empirical model of the osmotic dehydration of the unclassified tailings filter pipe in Jinshan Gold Mine is established, which provides the technical support for the filling and dewatering of the underground especially big empty area group.
